Sponge filter water fall?

[Canecorsonewt]

This might sound dumb but I'm still going to ask. I have a double sponge air filter with telescoping air outlet. When i pull the telescope over water level. Water pours out like waterfall. Can i make a waterfall out of this. Or does the air outlet need to be under water to work properly.

Yes, I use those filters in some of my tanks and you can make quite nice gentle waterfalls with the outlet. Basically, as long as there's water trickling out of the outlet, the filter is doing it's job. I've set mine up in the past so they trickle through the moss on bits of floating cork etc, it's also a good way of diffusing the current that many aquatic newts hate so much.
